background: combination of glycation and oxidation is associated with diabetes mellitus. the aim of this study was to clarify the effect of glycated proteins in presence of transition metal ions on production of reactive oxygen species (ros) in rat hepatocyte suspension.  methods: glycated albumin was prepared by incubation of bovine serum albumin with 100 mm glucose in 0.3 m phosphate buffer a...

A fundamental requirement for cellular vitality is the maintenance of plasma ion concentration within strict ranges. It is the function of the kidney to match urinary excretion of ions with daily ion intake and nonrenal losses to maintain a stable ionic milieu. NADPH oxidase is a source of reactive oxygen species (ROS) within many cell types, including the transporting renal epithelia. The focu...

Multiple lithium-ion transport pathways and local phase changes upon lithiation in silver hollandite are revealed via in situ microscopy including electron diffraction, imaging and spectroscopy, coupled with density functional theory and phase field calculations. We report unexpected inter-nanorod lithium-ion transport, where the reaction fronts and kinetics are maintained within the neighbouri...

Improved hybrid polymer electrolyte membranes are introduced based on ether-modified polysiloxanes and poly(vinylidene fluoride-co-hexafluoropropylene) yielding a safe separator membrane, which is able to be sprayed directly onto lithium ion battery active materials, with an active role for enhanced ion transport.

Poly(3-hydroxybutyrate) (PHB) is a polyester of 3-hydroxybutyric acid (HB) that is ubiquitously present in all organisms. In higher eukaryotes PHB is found in the length of 10 to 100 HB units and can be present in free form as well as in association with proteins and inorganic polyphosphate. It has been proposed that PHB can mediate ion transport across lipid bilayer membranes. We investigated ...

Membrane parameters characteristic for the study of electrolyte solutions across microporous membranes such as salt permeability, ion transport numbers and membrane electrical resistance have been determined for a ceramic microfiltration membrane by measuring salt diffusion, membrane potential and impedance spectroscopy (IS), respectively. In order to see the effect of ion charge and concentrat...

This work focuses on identifying the rate-determining step of oxygen transport through La0.5Sr0.5Fe0.7Ga0.3O3-? membranes with symmetric and asymmetric architectures. The best semipermeation fluxes are 3.4 10?3 mol. m-2.s-1 6.3 at 900 °C for membrane a modified surface. surface leads to an increase approximately 7 times flux compared that obtained dense without modification. also shows is mainl...
